Physiology of Memory

Certain areas of the brain are believed to be involved in memory processing, like the amygdala (emotional memory), hippocampus(declarative learning) and mammillary bodies.To determine which areas of the brain are involved in memory processing, researchers study animal models and patients with damage to those brain areas. Memory, however, is not dependent on a particular region; adjacent areas and pathways and synaptic changes are also implicated in learning and memory. Memory building starts with encoding, which is the perception of data through smell, sound, taste, touch and sight. Information is then encoded and stored in the form of electrical charges and chemicals. Communication between neurons (brain cells) occurs via the synapse, the spaces between neurons and center of brain activity. The firing of pulses across the synapse triggers the release of chemical messengers called neurotransmitters, which attaches to neighboring cells. These power linkages form a network between cells and groups of…
